fication on the ground of structure, appears to lie in the acceptance of 
Bullion's suggested name, giving 1 up that of the authors of the Flora 
The syuonymy of G natter ia is further complicated by the fact that 
a large number of Hpecies with valvate aestivation were referred to it 
by Wallich and others. These, however, were separated by Hook fil. and 
Thorns, by whom the genus Polyalthia was formed for their recep- 
tion. Sir Joseph Hooker refers to Cauanga, not only the species O. 
odorata^ but nnother named 0, virgata. The latter plant appears to me, 
in the light of full material recently received, to be a typical Cyath oca lip', 
and to that genus I have ventured to remove it. A third species doubt- 
fully referred to t.he genus Cauanga nnder the specific name monosperma y 
appears to me from the description (I have seen no good specimen) to 
he so don hi ful that I exclude it altogether. The seeds both of this 
species and of G. Odoratum are peculiar; I quote the following excel- 
lent description of those of 0. odoratum from Hooker fil. and Thomson's 
Flora Indrca, page 130. li The seeds are pitted like those of the section 
Kentia of Melod&rum^ and of some Cucurbit lacem ; and the inner surface 
of the brownish-yellow, brittle testa in covered with sharp tubercles, 
which penetrate into the albumen, taking the place of the flab plates 
which are found in the rest of the order."
